Abstract: A flow probe for use in a humidification system is disclosed. The flow probe is adapted to be positioned in a humidified gases flow (for example oxygen or anaesthetic gases) such as that which is provided to a patient in a hospital environment. The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors (preferably thermistors) and the shape and alignment of the probe enables accurate readings by reducing the occurrence of condensation on the sensors. A number of possible applications are disclosed wherein the flow sensor is included in humidification control systems which provide a patient with a desired humidity level or simplify the amount of user input required or wherein the flow sensor provides a controller with flow information which may then be used to determine certain, possibly dangerous, conditions (such as incorrect flow sensor placement, breathing circuit disconnected, no water in the humidification chamber or humidity out of required limits).

Abstract: Tampon hygiénique et son procédé d'élaboration. Ce tampon est utile pour empêcher la fuite prématurée de liquide corporel depuis le vagin de la femme, particulièrement, pendant la période menstruelle. Ce tampon comprend une couverture absorbante et perméable aux liquides. Cette couverture entoure au moins partiellement l'absorbant et ils constituent ensemble un rouleau mou possédant une première et une deuxième extrémités. On enroule ce rouleau mou sur lui-même au niveau de trois emplacements espacés les uns des autres, afin de constituer un profil en forme de M. On comprime ensuite ce profil en forme de M en un tampon cylindrique possédant une extrémité d'insertion et une extrémité arrière. L'extrémité d'insertion contient une quantité plus importante d'absorbant que ladite extrémité arrière et comporte une fente obtenue sous l'effet du pliage. Cette fente provoque la dilatation latérale du tampon immédiatement à l'insertion du tampon dans le vagin. Ce tampon comprend, de plus, un cordon de retrait qui facilite l'enlèvement du tampon du vagin. Ce procédé consiste à découper des éléments individuels absorbants dans une bande absorbante. On met en forme chaque élément afin d'obtenir un absorbant allongé possédant une périphérie extérieure. On fixe une couverture perméable aux liquides à la périphérie extérieure de l'absorbant allongé afin de créer un rouleau mou. Ce dernier possède une première et une deuxième extrémités. On le plie ensuite sur lui-même, de manière  à aligner la première et la deuxième extrémités contiguës l'une à l'autre et de telle sorte que le rouleau contienne au moins trois enroulements. On comprime ensuite ce rouleau afin d'obtenir un tampon et on fixe le cordon de retrait, ce qui permet de créer un tampon hygiénique. Dans un autre mode de réalisation, on peut fixer le cordon de retrait au rouleau avant la compression. Ce cordon facilite le retrait du tampon depuis le vagin.

Abstract: A method and apparatus for determining whether a wireless station is operating within a prescribed geographic location. During an initialization process, the wireless telephone measures propagation delays of pilot signals from nearby base stations and stores the propagation delays in a non-volatile memory of the wireless station. Thereafter, during a check process, the wireless station measures propagation delays of pilot signals from nearby base stations and compares them with the stored propagation delays stored in memory. If the difference between the two sets of propagation delays are within a predetermined tolerance, then a determination is made that the wireless station is operating within the prescribed geographic location.      Multiple sets of propagation delays may be stored in memory such that a determination can be made as to whether the mobile station is operating within any one of a number of prescribed geographic locations.

Abstract: Systems, processes, and devices are provided which are useful for testing blood or plasma donations to detect those specific donations which are contaminated by a virus above a predetermined level. An apparatus and process is described which forms individual, separately sealed and connected sample containers from a flexible hollow tubing segment connected to a fluid donation container. The tubing segment is sealed at spaced-apart intervals along its length, with tubing segment portions in the intervals between the seals defining containers, each of which holds a portion of a plasma sample. The contents of the containers are formed into pools which are subsequently tested for virus contamination by a high-sensitivity test such as PCR. The pools are tested in accordance with an algorithm by which a sample from each donation is mapped to each element of an N-dimensional matrix or grid. Each element of the matrix is identified by a matrix identifier, X rcs, where rcs defines the dimensional index. An aliquot is taken from each sample, and subpools are formed, each subpool comprising aliquots of samples in which one dimensional index is fixed. All of the subpools are tested in one PCR test cycle. The dimensional indicia of each positive subpool is evaluated mathematically in accordance with a reduction by the method of minors, thereby unambiguously identifying a unique element in the grid, thereby unambiguously identifying a uniquely positive blood or plasma donation.

Abstract: A combination infrared/convection dryer or oven (10) for drying travelling webs (W). A shutter assembly (8) is provided between the infrared radiation source (16) and the moving web in order to selectively expose the web to infrared radiation. Drying efficiency is optimized by adding heated impinged air at high velocity on the machine direction ends and between the infrared elements. The air being discharged on the web is heated as it is pulled gross the elements to a centralized return air duct (42). The return air is pulled into the inlet of a close coupled supply fan (28) which then discharges the air to the nozzles. A portion of the air is also exhausted at atmosphere to maintain the oven enclosure in a negative pressure state, thus drawing fresh make-up air into the oven housing through the web inlet (12) and outlet (13) slots. Flotation nozzles (151, 152) can be used where contactless support of the running web is desired. Enhanced drying of the web and/or a coating on the web at high speed is achieved without a concomitant increase in dryer length.

Abstract: A combined, parallel adaptive equalizer/echo canceller is disclosed. The equalizer/canceller receives at least one input signal which is split into n taps. The n taps are multiplied by corresponding n tap coefficients to produce n tap output signals. The n tap output signals are then processed through an additive pipeline to produce a filter output signal. The additive pipeline provides low latency by processing the nth most recent tap output signal n clock cycles from the filter output signal. The combined FIR filter structure is made fully adaptive using delayed LMS coefficient adaptation. Tap coefficients are updated using an error signal and delayed versions of the input signal. The error signal is a product of a calculated error and a negative adaptation factor. The delay is equal to a sum of n+1 cycles.

Title: Wavelength-selective optical add/drop using tilting micro-mirrors
Inventor: TOMLINSON W JOHN
IPC: H04J14/02
Filed: 1999-01-27
Granted: 2003-08-12
Abstract: An optical switch particularly usable as a wavelength-division add/drop multiplexer (WADM) in a multi-wavelength communication system. Four multi-wavelength beams optically coupled to the input, output, add, and drop channels are arranged in parallel in a rectangular array and are incident upon a diffraction grating. The grating operating in one direction disperses the beams into their wavelength components and operating in the other direction recombines the wavelength components into a multi-wavelength beam. A lens focuses the components of the beams having a particular wavelength upon one of an array of tiltable micro-mirrors integrated on a silicon substrate. In one position, the mirror for a particular wavelength reflects that wavelength component from the input beam back to the output beam. In a second position, that mirror reflects that wavelength component from the input beam back to the drop beam and reflects that same wavelength component from the add beam back to the output beam. The same optics can be used for a second set of beams which are switched in synchronism with the first set. The array of mirrors can be fabricated to be tiltable to more than two positions so that the input beam can be selectively coupled to either the output beam or one of at least two drop beams while the ouput beam is correspondingly selectively coupled to either the input beam or one of at least two add beams.
